Note 1:
These devices are bidirectional only. Electrical characteristics apply in both directions. The monolithic TVS array is based on 10 unidirec-
tional P/N junctions with a common cathode and can be configured to offer 8 to 9 bidirectional lines of protection. The inputs are symmetrical and can
be reversed for specific application layout requirements.
